` This invention relates to heaters as boilers for heating buildings and has for its object a particularly simple and efficient means for adjustingthe boilersfor burning different kinds of fuel, andfor also adjusting the amount of fuel to be consumed in the boilers; andthe vinvention consists in the novel' combination and construction hereinafter set forth and claimed.

In describing this invention reference i s had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a front elevation of a sectional boiler embodying my invention.

Fig. 2 is a vertical sectional view thereof.

This heater comprises generally a boiler having a vertical fuel passage, a wall of the passage being adjustable to vary the size and shape of the passage. This wall is usually adjustable rectilinearly or about axes located at its upper and lower ends.

I have here illustrated my invention as embodied in that type of heaters known as sectional boilers which are composed of end sections 1, and intermediate sections 2, which may be of any suitable form, size and con-j struction. The end sections are usually formed with portions or projections 3 extending in front of the front edges of the intermediate sections, and the front wall is located between the projections 3 and opposed to the front ends of the intermediate sections, forming a vertical fuel passage 4 at the lower end of which the grate 5 is located. A hopper 6 is located at the upper end of said passage.

7 is a wall opposed to the front walls of the intermediate sections and located between the extensions 3 of the end sections and formin the front side of the passage 4, this wall eing adjustable forwardly and rearwardly to regulate the size of the passage 4. This wall is preferably formed hollow and is what is usually known as a water front and the interior thereof is connected to the interior of the end sections by pipes 8, 9 connected to the upper and lower ends Specification of Letters Patent.,

thereof, these pipes including sections 10, 11 about which either end of the water front may swing about as axes and also includlng sections which are joined by sleeve nuts .12 by means of which the pipes can be adjusted in lengthwise directions. By manipulation of the sleeve nuts, the water front may be adjusted rectilinearly, forwardly and rearwardly or either end thereof may be adjusted about the pivot at the other end, the -movement of the water front being permitted bv the slots 13'in the extensions 3 through which slots the pipes extend.

Thewater front is also providedv with a down draft passage 14 having laterally extending and downwardly inclined blanches 14 opening into thepassage 14.

The adjustable water front is connected t0 the hopper by adjustable connections consisting of wall sections 1G, 17 pivoted rcspectively at 1S and 19 to the hopper 5 and the water front 7, these wall sections lapping each other and being connected by a pin-and-slot connection 20.

During the adjustment of the water front 7, the lapping portions of the wall sections 16, 17 will slide relatively to each other;

By manipulating the sleeve nuts 12 and swinging the water front 7 about either of its axes 10, 1l or by moving the water front rectilinearly inwardly or outwardly the size and shape of the passage 4 can be adjusted to suit the kind or quantity of coal t0 bev used. The slots 13 are closed by the usual asbestos or other plastic covering of the boiler.

What I claim is:

1. A boiler having a vertical fuel passage, a water wall connected to the boiler` and forming one of the walls of the fuel passage and forming a fuel magazine, the water wall being pivoted and adjustable on its pivot, and water pipe connections connected to the water wall at a point remote from its pivot, said pipe connections being adjustable to conform to the pivotal adjustment of the water wall, substantially as and for the purpose described.

2. A heater having a vertical fuel passage and a wall forming one side of the passage, said wall being pivoted at its upper and lower ends and adjustable rectilinearly forwardly and rearwardly or adjustable about either one of its pivoted ends, substantially as and for the purpose specified.

3l A boiler having a vertical fuel passage, a hollow water wall connected to the boiler and forming one of the walls of the fuel passage, and pipes connecting the opposite ends of said hollow wall and the boiler, the wall being adjustable forwardly and rearwardly, and said pipes being pivotally connectedV to opposite ends of said wall and beingV adjustable in a lengthwisedirection, substantially as and for thepurpose set forth.

4. A boiler having a fuel hopper, a vertically extending fuel passage leading from i the hopper, the outer wall of the passage being adjustable inwardly and outwardly toward and from the body of the boiler to narrow or widen said fuel passage, a wall connecting the former wall and the hopper to permit the adjusting movement of the former wall, said connecting wall including sections hinged respectively to the hopper and to the former wall, the sections lapping each other during the adjustment of the former wall, and means for holding the lapping portions from separation, substantially as and for the purpose specified.

5. A sectional boiler comprising end sections which project in front ofthe intermediate sections, a hollow water front interposed between the front ends of the end sections and forming a vertical fuelpassage, a hopper above the fuel passage and adjustably connected to the water front, said'water front being adjustable forwardly and rearwardly, and pipes connecting the end sections and the water front, the pipesv being pivotally connected to the upper and lower ends of the water front and being adj ustable in lengthwise directions, substantially as and for the purpose set forth. j In testimony whereof, I `have hereunto signed my name, at Syracuse, in the county of Onondaga, and State of New York, this 17th day of January, 1916. p
